The blocking member 150 can be movably assembled with the stand 102 . For example, the blocking member 150 may be pivotally connected to the stand 102 , such as the support platform 124 or the calf support 126 of the stand 102 . According to one embodiment, the blocking member 150 may include a rod extending transversely generally along the width direction of the seat 104 , with two opposite ends of the rod pivotally connected to the calf support portion 126 of the stand 102 . Thereby, the blocking member 150 is rotatable about a pivot axis R extending laterally from the left side to the right side of the seat 104 between a blocking position and a release position. According to one embodiment, the barrier 150 may be disposed adjacent the calf support 126 .

The blocking member 150 can engage with the seat 104 during the rotation of the seat 104 from the first position toward the second position, so as to urge the seat 104 to stop at the intermediate position but allow the seat 104 to pass through the intermediate position from the second position. Rotate continuously to the first position. For example, the blocker 150 may have two bends 158 protruding above the rod segment 122 and the support platform 124 and radially offset by the pivot axis R of the blocker 150 , while the seat 104 may have two hooks 160 (best shown in FIG. 2 ), the hook portion 160 can move together with the seat 104 and can engage and disengage with the two bending portions 158 respectively. When the seat 104 rotates from the first position to the second position, through the engagement of the hook portion 160 and the bending portion 158, the blocking position of the blocking member 150 can cause the seat 104 to stop at the first position and the second position. The middle position between positions. The intermediate position forms an included angle of about 15 degrees with the first position, for example. During the rotation of the seat 104 from the second position toward the first position, the hooks 160 can respectively contact and push the bending portions 158 so that the blocking member 150 is pushed by the seat 104 to rotate from the blocking position to the releasing position to allow The seat 104 continues to travel through the intermediate position to the first position.

The spring 152 is shown in dashed lines in the enlarged view of FIG. 8 . Referring to Figures 2 and 8, the spring 152 can force the blocking member 150 to move toward the blocking position. According to one embodiment, the spring 152 may be a compression spring that is connected to the stand 102 (eg, the support platform 124 or the calf support 126 of the stand 102) and the blocker 150, respectively. More specifically, the spring 152 may be disposed adjacent to the latch 154 , for example.

The locking member 154 can be connected with the blocking member 150 . For example, the release member 154 may be fixed to the blocking member 150 at an intermediate position between the two bends 158 . The release part 154 can be operated to cause the blocking part 150 to overcome the elastic force of the spring 152 and rotate from the blocking position to the releasing position, so that the bent part 158 of the blocking part 150 is disengaged from the hook part 160 of the seat 104 .
